Y Specification of Letters Patent. Patented J an. 24:, 1911.

Application filed March 27, 1906. Serial No. 308,375.

To all whom it may concern:

Be it known that I, WILLIAM A. DAwsoN, a citizen of the United States,residing at Iola, in the county of Allen and State of Kansas, haveinvented a new and useful Motor-Plow, of which the following is a.

specification.

This invention relates to motor. propelled machines and moreparticularly to means whereby the direction of the movement of themachines can be readily controlled, said means being actuated by thedriving holder. Another object is to provide a machine of this ty ehaving tilling devices mounted upon the rent portion thereof, meansbeing utilized whereby the positions of these devices, with relation tothe supporting structure, may be conveniently varled by the operator.

Further 'objects are to improve upon the construction and increase theefficiency and utility of devices of this character.

With these and other objects in View the invention consists of certainnovel details of construction and combination of parts hereinafter morefully described and pointed out in the claim.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings, Figure l is a plan view of the complete machine. Fig.2 is a side elevation thereof. Fi 3 is a perspective view of a modifiedorm of extenslon of frame for use in connection with the maerablyrectangular in outline, and having a longitudinally extending beam Csecured along the center thereof, said beam coopcrating with atransverse beam B to support the motor K which is of any desiredconstruction.

Alining, transversely extending axles B are journaled within the sidesof the frame A and within the central longitudinally extending beam 0,each of these axles being provided with a series of supporting wheels,D, E, F and G. The rims of these wheels are preferably triangular incross section and formed of segments (see Fi 2) and if desired, pins Hmay be exten ed radially from the periphery of each Wheel soas topositively engage the ground and thus prevent the wheels from slippingwhile the machine is being propelled. In Fig. 1, only two of the wheelshave been shown provided with these pins but it is to be understood thatall, or any desired number mtg be so provided. I

orner posts a are mounted on the frame A and support a top frame 11 onwhich are arranged longitudinally extending beams 11 on which arejournaled alinin shafts A, eachoof which is provided upon 1ts ends, withsprockets A, designed to transmit motion through chains a, to sprocketsA- secured to the end ortions of the axles. Each shaft A is provi edwith a beveled gear A", meshing with a gear A, this last mentioned gearbeing secured upon a longitudinally extending shaft A which is journaledin a supporting frame (1*, located within the to frame 11. A gear A issecured to the sha A and meshes with opposed gears W and which areloosely mounted on an intermediate shaft Q, which is journaled upon the.

top frame 11 near the auxiliary frames (1 A clutch V is feathered on theshaft Q between each pair of gears W and Z and is designed to e actuatedby a lever X or Y so as to engage either of the gears W and Z,

to cause one or the other of the gears to rotate with the shaft Q.

Gears R and S of different diameters are loosely mounted on the shaft Qand clutch members T are feathered on said shaft and are loosely engagedby a yoke a formed at one end of a rod U which is pivotally connected toan actuating lever U By mani ulating this lever one clutch member T W1 1be brought into engagement with the ad'- joining gear so as to lock itto the shaft Q. A counter shaft N is j ournaled on the beams 11 and hasgears O and P secured to it, said gears being of different diameters,the smaller gear P being constantly in mesh with the large gear R, whilethe gear 0 is at all times in mesh with the gear S. A pulley M issecured on the shaft N and receives motion through a belt or the like,from a pulley L secured to the engine of the shaft.

.It will be understood that motion will be locked to it. If the clutchmembers V are -in the paths thereof will be locked to the shaft Q andwill therefore drive the gears A meshing therewith and cause theshafts Aand A to rotate. Motion is thus trans-' mitted through sprockets andchains to the axles B. By shifting the clutch members V in oppositedirections the rotation of the supporting wheels can be reversed and byshifting the two clutch members simultane ously in opposite directionsthe two sets of wheels can be simultaneously rotated in oppositedirections, thus. insuring quick turning of the machine.

As herebefore stated, it is the intention to place the tilling devicesin front of the main frame so that they will be pushed forward duringthe operation of the machine and be in full view of the operator. Inorder to mount a gang of ner, a substantially triangular auxiliary frameJ is secured to the front end of the main frame .A and the diagonallydisposed side of this auxiliary frame has the plows 2 connected to it.

A caster 3 may be located at the apex of the frame and the shank thereofmay have a worm gear 4 attached to it, this worm gear meshing with aworm gear 5 secured to one end of the shaft 5. As shown, especially inFig. 2, this shaft is journaled upon the frame J and also upon the topframe 11 and has any suitable means such as a hand wheel 6, foractuating it.

A winding shaft A may be journaled upon standards A extending from thedi agonal side of the frame J, there being flexible connections 1between the shaft and the standards of the plows 2 so that when theshaft is rotating, the connections 1 will be wound thereon and thestandards and plows elevated. The shafts A may be actuated in anypreferred manner, as by means of a shaft a having a gear a thereon tomesh with a gear a which is secured on the shaft A". The shaft a may beactuated by means plows in this man-' of a wheel 6 or in any otherpreferred manner.

The auxiliary frame J is preferably provided with a suitable series ofbraces so as to enable the same to better withstand the excessive strainto which the frame is subjected during the tilling of the soil.

A frame J such as is shown in detail in Fig. 3 maybe secured tothe'front end of the main frame A when it is desired to carry lng arms J2 for attachment to frame A and may be shaped to meet the requirementsof a harvester coupling. This frame J preferably includes heavy parallelbars suitably connected, as at J the connections being formed withopenings j for the reception of securing bolts.

Attention is directed to the fact that the combined widths of the wheelsD, E, F and G are substantially equal to the width of the area actedupon by the plows 2, the triangular rims 7 operating to. roll the plowedground and to form ridges.

Various changes may be made in the construction and arrangement of partswithout departing from the spirit or sacrificing any of the advantagesof the invention.

\Vhat is claimed is A machine of the class described including a mainframe, spaced series of supporting wheels therefor, all of said wheelsconstituting furrow forming devices, radial projections upon one wheelof each series for engaging the soil to prevent the wheels fromslipping, a motor, and separate means actuated by the motor for rotatingthe respective series of wheels.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature in the presence of two witnesses.
